in rule.yml file:

• rule: out-of-scope

steps: - intent: nlu_fallback - action: utter_out_of_scope

domain.yml file:

intent section:

• out_of_scope

response section:

• utter_out_of_scope:

    - text: Sorry, I didn't get what you said. Please rephrase what you said.
    ```

[@subbu_y80](https://forum.rasa.com/u/subbu_y80),did you retrain your model? Check out the docs [about how to implement fallback.](/content/docs/rasa/fallback-handoff#1-creating-an-out-of-scope-intent/index.html)

You could run rasa shell --debug to check what intent your assistant is recognizing. Even run rasa interactive and teach your bot what kind of expressions are out of scope and how it should respond.
